An Analysis of the Exposure History of Apollo 17 Soils: Exploring Relationships Between Lunar Soil Maturity Indices

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Analysis of space weathering features in lunar regolith using transmission electron microscopy (TEM) allows researchers to characterize the surface exposure timescale of individual grains from the Moon. TEM analysis of regolith grains from Apollo 17 scoop samples, collected from five different locations in the Taurus‐Littrow Valley (TLV), each

A Fluvio‐Lacustrine Environment Preserved in the Jezero Crater Inlet Channel, Neretva Vallis, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian fluvial valleys provide evidence for the surface flow of liquid water, making them a key target for rover‐based investigations of ancient habitability. The Mars 2020 Perseverance rover spent ∼85 sols exploring the Bright Angel formation, exposed across the floor of Neretva Vallis: the western inlet channel of Jezero crater.

Field Observations of Decreasing Rock Fracturing Rates Over Geologic Time

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.
Abstract Rock fracturing regulates the topography, carbon cycle, geologic hazards, and infrastructure degradation of the Earth. Yet, there remains a paucity of constraints on long‐term fracturing behavior. Here we use field measurements of 2221 clasts across a range of environments and rock types to show that the number and total length of fractures in

Environmental Controls on the Cycling of Fe and Mn in Patagonian Fjord Systems

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Fjord sediments are important reservoirs and conduits of potentially bioavailable iron (Fe) and manganese (Mn). Both elements are critical to life, serving as key reactants in metabolic pathways, and play an important role in the reactivity and burial of organic carbon.

Bridging Ecology and Geosciences in Riverscapes: Implications for Process‐Based Restoration

Ecological Research, Volume 41, Issue 1, January 2026.
In this paper, we synthesize studies that integrally examine geological and ecological processes across different scales and components of riverscapes, including geohydrological processes. Finally, we identify both scientific and practical challenges that must be addressed to bridge the gap between basic‐science implications and their implementation in
